Super Foreverspin Base
thingiverse
By shrinking the model to 97.5% scale the 75mm lenses from Amazon fit wonderfully (as seen in the picture) (http://a.co/dEFFzYI). Otherwise the STL as it is should fit the foreverspin base but I don't have one anymore to test fitment. I really enjoyed the base model but my top collection grew too large to display. I used TinkerCAD to superimpose two of the models over each other and rotated to align the base hole and two of the top holes. Alignment is not 100% but the printed piece is near impossible to see any imperfection.
